  "abstract": "Two theorems with applications to the quantum theory of measurements are stated and proven. The first one clarifies and amends von Neumann's Measurement Postulate used in the Copenhagen interpretation of quantum mechanics. The second one clarifies the relationship between ``events'' and ``measurements'' and the meaning of measurements in the $ETH$-Approach to quantum mechanics.",
